Winning Mega Millions tickets were purchased in Kansas, Illinois and Maryland, the Associated Press reported. The ticket holders will split the $640 million jackpot, perhaps the largest such prize in history, a lottery official said. The winning numbers were 46, 23, 38, 4, 2 and Mega Ball 23.

The prize is so large as more than one billion lottery tickets were sold, according to lottery officials. An addition $300 million was added since the last Mega Millions drawing last Tuesday failed for the 18th consecutive time to find a winner, USA Today reported. The jackpot has been growing since Jan. 24, when the current total began growing. In the past 24 hours, the jackpot grew by $100 million.

According to MSNBC, the previous Mega Millions jackpot record was $390 million. That prize was split by winners in Georgia and New Jersey.
